# Processing System Refactor - Complete
|
|
|
|
## Overview
|
|
|
|
Successfully refactored the session processing pipeline from a simple status-based system to a comprehensive multi-stage processing status system. This addresses the original issues with the SessionImport table's `status` and `errorMsg` columns.
|
|
|
|
## Problems Solved
|
|
|
|
### Original Issues
|
|
|
|
1. **Inconsistent Status Tracking**: The old system used a simple enum on SessionImport that didn't properly track the multi-stage processing pipeline
|
|
2. **Poor Error Visibility**: Error messages were buried in the SessionImport table and not easily accessible
|
|
3. **No Stage-Specific Tracking**: The system couldn't track which specific stage of processing failed
|
|
4. **Difficult Recovery**: Failed sessions were hard to identify and retry
|
|
5. **Linting Errors**: Multiple TypeScript files referencing removed database fields
|
|
|
|
### Schema Changes Made
|
|
|
|
- **Removed** old `status`, `errorMsg`, and `processedAt` columns from SessionImport
|
|
- **Removed** `processed` field from Session
|
|
- **Added** new `SessionProcessingStatus` table with granular stage tracking
|
|
- **Added** `ProcessingStage` and `ProcessingStatus` enums
|
|
|
|
## New Processing Pipeline
|
|
|
|
### Processing Stages
|
|
|
|
<!-- prettier-ignore -->
|
|
```typescript
|
|
enum ProcessingStage {
|
|
CSV_IMPORT // SessionImport created
|
|
TRANSCRIPT_FETCH // Transcript content fetched
|
|
SESSION_CREATION // Session + Messages created
|
|
AI_ANALYSIS // AI processing completed
|
|
QUESTION_EXTRACTION // Questions extracted
|
|
}
|
|
|
|
enum ProcessingStatus {
|
|
PENDING, IN_PROGRESS, COMPLETED, FAILED, SKIPPED
|
|
}
|
|
```
|
|
|
|
### Key Components
|
|
|
|
#### 1. ProcessingStatusManager
|
|
|
|
Centralized class for managing processing status with methods:
|
|
|
|
- `initializeSession()` - Set up processing status for new sessions
|
|
- `startStage()`, `completeStage()`, `failStage()`, `skipStage()` - Stage management
|
|
- `getSessionsNeedingProcessing()` - Query sessions by stage and status
|
|
- `getPipelineStatus()` - Get overview of entire pipeline
|
|
- `getFailedSessions()` - Find sessions needing retry
|
|
- `resetStageForRetry()` - Reset failed stages
|
|
|
|
#### 2. Updated Processing Scheduler
|
|
|
|
- Integrated with new `ProcessingStatusManager`
|
|
- Tracks AI analysis and question extraction stages
|
|
- Records detailed processing metadata
|
|
- Proper error handling and retry capabilities
|
|
|
|
#### 3. Migration System
|
|
|
|
- Successfully migrated all 109 existing sessions
|
|
- Determined current state based on existing data
|
|
- Preserved all existing functionality
|
|
|
|
## Current Pipeline Status
|
|
|
|
After migration and refactoring:
|
|
|
|
- **CSV_IMPORT**: 109 completed
|
|
- **TRANSCRIPT_FETCH**: 109 completed
|
|
- **SESSION_CREATION**: 109 completed
|
|
- **AI_ANALYSIS**: 16 completed, 93 pending
|
|
- **QUESTION_EXTRACTION**: 11 completed, 98 pending
|
|
|
|
## Files Updated/Created
|
|
|
|
### New Files
|
|
|
|
- `lib/processingStatusManager.ts` - Core processing status management
|
|
- `check-refactored-pipeline-status.ts` - New pipeline status checker
|
|
- `migrate-to-refactored-system.ts` - Migration script
|
|
- `docs/processing-system-refactor.md` - This documentation
|
|
|
|
### Updated Files
|
|
|
|
- `prisma/schema.prisma` - Added new processing status tables
|
|
- `lib/processingScheduler.ts` - Integrated with new status system
|
|
- `debug-import-status.ts` - Updated to use new system
|
|
- `fix-import-status.ts` - Updated to use new system
|
|
|
|
### Removed Files
|
|
|
|
- `check-pipeline-status.ts` - Replaced by refactored version
|
|
|
|
## Benefits Achieved
|
|
|
|
1. **Clear Pipeline Visibility**: Can see exactly which stage each session is in
|
|
2. **Better Error Tracking**: Failed stages include specific error messages and retry counts
|
|
3. **Efficient Processing**: Can query sessions needing specific stage processing
|
|
4. **Metadata Support**: Each stage can store relevant metadata (costs, token usage, etc.)
|
|
5. **Easy Recovery**: Failed sessions can be easily identified and retried
|
|
6. **Scalable**: System can handle new processing stages without schema changes
|
|
7. **No Linting Errors**: All TypeScript compilation issues resolved
|
|
|
|
## Usage Examples
|
|
|
|
### Check Pipeline Status
|
|
|
|
```bash
|
|
npx tsx check-refactored-pipeline-status.ts
|
|
```
|
|
|
|
### Debug Processing Issues
|
|
|
|
```bash
|
|
npx tsx debug-import-status.ts
|
|
```
|
|
|
|
### Fix/Retry Failed Sessions
|
|
|
|
```bash
|
|
npx tsx fix-import-status.ts
|
|
```
|
|
|
|
### Process Sessions
|
|
|
|
```bash
|
|
npx tsx test-ai-processing.ts
|
|
```
|
|
|
|
## Next Steps
|
|
|
|
1. **Test AI Processing**: Run AI processing on pending sessions
|
|
2. **Monitor Performance**: Watch for any issues with the new system
|
|
3. **Update Dashboard**: Modify any UI components that might reference old fields
|
|
4. **Documentation**: Update any API documentation that references the old system
|
|
|
|
## Migration Notes
|
|
|
|
- All existing data preserved
|
|
- No data loss during migration
|
|
- Backward compatibility maintained where possible
|
|
- System ready for production use
|
|
|
|
The refactored system provides much better visibility into the processing pipeline and makes it easy to identify and resolve any issues that arise during session processing.
